STEAM-DRIER.

SPECIFICATION forming part of Letters Patent No. 685,154, dated October22, 1901.

To all whom it may concern.-

Be it known that I, WILHELM LEWY, man ufacturer, of Warsaw, Poland,Russia, have invented a Steam-Drier, of which the following is aspecification, reference being had therein to the accompanying drawings.

The object of the following invention is an apparatus for extracting theportion or particle of water from the boiler caused by the developmentof the steam and is effected by means of the arrangement of a case orreceptacle suitable for the interior of the boiler, in which one or moreplate-shaped disks are arranged containing a center waste pipe. Thesteam entering into the case or receptacle is compelled to strikeagainst the disks, whereby the particles of water contained in the steamare extracted as the same in striking are forcibly whirled up. By meansof the centrally-arranged waste-pipe the extracted water flows back tothe water in the boiler, while the dry steam is conducted to itsrequired position by means of a suitable conductor.

In the accompanying drawings, Figure 1 shows the steam-extractingapparatus in sectional elevation, while Fig. 2 shows it in plan, part insection, in the line a b of Fig. 1. Figs. 3, 4, and 5 are modificationsof the apparatus in section intended for use upon moving vehicles orwhen the device is subject to vibration.

In the cylindrically-formed case or receptacle, according to Fig. 1, thetwo plate-shaped disks a and c are accommodated. The disk 6 consists ofa conical part b, to which the arched bow 11 applies. To the bow b isfastened the central waste-pipe d, which extends downward in the disk 0.The disk 6 is, by means of the lever-piece a, suspended in the case orreceptacle. The steam-entrance into the case or receptacle is efiectedthrough the funnel-shaped opening g in the covering r.

Below the disk I) is shown the disk 0, this consisting of the portion 0,corresponding to portion I), and bow 0 corresponding to bow b and,furthermore, of a center waste-pipe It. By means of the four waste-'pipes 'i, which extend downward from the partitions 7c of the case orreceptacle, the disk 0 is held in its position. In the partition isshown an other funnel-shaped opening Z besides the opening g. On theground or base of the case or receptacle a rests the cylinder por tionm, in which the pipe or tube It extends to the ground. On the latter(inclosed) is fastened the waste-pipe n, the length of which is sodetermined that a certain portion extends into the water in the boiler.To the portion m, furthermore, is attached the steamconducting pipes ortubes 19, (represented with aflanger.) Thewater-conductingpipeortube n,furthermore, carries a cap 8 at its lower end, which by the eventualsinking of the waterlevel guards against all escape, so that the steamcan enter into the pipe or tube.

The mode of operation of the whole apparatus is as follows: Through theinlet or opening g the steam enters the apparatus and strikes againstthe plate-formed arched bows b of the disk I), is here whirled upward,and drawn in the direction indicated by the arrow over the conicalportion 19 away downward. The particles of water hereupon becomeseparated and flowofi through the central pipe downward. The steamitself is forced downward, partly through the tube 2' and partly throughfunnel-shaped opening Z, and comes into contact with the bows c of thedisks 0, is here whirled upward, and travels in the direction of thearrows over the conical portion 6' downward, while the extracted waterflows downward through the tube h. The water from the tube 61 as thesame passes a narrow transverse cutting flows over into the tube It inorder to enter into the water in the boiler through the pipe n. Thesteam which is now comparatively free from the molecules of water drawsoff through the tube p.

Oorrespondingly the whole apparatus is so suspended in the boiler thatthe space between the steam-extracting pipe and the underneathwater-play is five hundred millimeters. The apparatus itself can receivea befittingly-da pressed form and can be applied to any desired boilerWithout fearing that abatement of pressure can cause an entering ofwater from below through the tube a. The latter can therefore not enter.Because the pipes d, h,

and n communicate with one another the pressure on the water in thetubes at g is exactly the same as the exterior. The water in the tube inentering into the case or receptacle if the pressure is momentarilyabated is not in the position to reach high up in the tube 7L.

A modification of this apparatus is shown in Figs. 3, 4, and 5, which isespecially characterized by the fact that by the combination of thisapparatus with a steam-injector when the boiler is subject tovibrationsas, for in; stance,with 1ocomotive-boi1ersan ascension of thewater in the tube F, which projects into the boiler, is avoided and thepenetration into the drying apparatus proper cannot take place. Thedrying apparatus A corresponds, essentially, to that in thefirst-described form. The tube 0, corresponding to the tube It in theformer construction, projects into a chamber H, arranged in theapparatus. The steam-injector apparatus adjoins this chamber H. Thesteam enters the injector through the cone J and leaves it in thedirection of the arrow through the tube E, which in the present formopens out between the upper and lower disks. In the steam-drierapparatus the steam enters in the usual wellknown manner from above, sothat the water collects on the plate-shaped disks, and in the presentcase flows through the tube 0 into the box H. As the steam enteringthrough the cone J produces a rarefaction of the air in the spacebetween this cone J and the lower cone D the water which collects in thebox H will flow downward and reenter the boiler through the tube F. Thesteam passing through the cone D will exert a certain pressure upon thetube F and prevent the water from rising in the boiler into the boX H.

In Figs. 4 and 5 a further modification is shown which differsessentially from known arrangements by the fact that the steam-dryingapparatus proper is not provided with plate-shaped disks, but consistsonly of a conical chamber B, to which the injector apparatus is suitablyconnected, as shown in dotted lines in Fig. 4.. The steam enters thechamber B through openings x at the upper end. The openings are formedby tangential wings y, as shown in Fig. 5, which represents a section online a b. The steam entering through the openings :1; passes spirallydownward in the chamber B into the tube B. In consequence of thecentrifugal force arising the particles of water are thrown outwardlyand settle down in the bottom of the chamber, from whence they pass intothe injector through the openings 1;.

Instead of a common injector the known Korting injector can be used,which, in combination with the before-described appa ratus, will producethe same efiect.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is-

1. In an apparatus for drying steam a case or receptacle provided withone or more plateshaped disks 1), c, in combination with an outlet-pipefor the water,and an ejector arranged between said outlet-pipe and thedrying apparatus, whereby a rapid exhaust of the water from the injectoris obtained and the water prevented from rising in the outlet-pipe.

2. In an apparatus for drying steam a case or receptacle provided withone or 1n ore plateshaped disks 1), c, and'suitable waste-pipes, incombination with the tangential blades 1 arranged above the openings inthe cover of the device, whereby the steam is forced downward inspirals, thereby giving centrifugal motion to the steam to therebyseparate more eitectually the water from the steam.

3. In an apparatus for drying steam a case or receptacle, provided witha plate-shaped disk and a waste-pipe, in combinationwith an injectorlocated between the waste-pipe and the drying apparatus.

4. In an apparatus for drying steam, a case or receptacle provided withone or more plateshaped disks 1), c, and suitable waste-pipes, incombination with the tangential blades '1] arranged about the openingson the cover of the device, whereby the steam is forced down-
